IMPRO VEMENT IN HYDRAULIC HOSE.

' Specification forming part of Letters Patent No. 165, [59, dated J nly6, 1875; application filed May 22, 1875.

To all whom it may concern: Be it known that I, LEVERETT H. Down- ING,of North Andover, in the county of Essex and State of Massachusetts,have invented a new and useful Improvement in Hydraulic Hose; and dohereby declare the same to be fully described in the followingspecification and represented in the accompanying drawings, of which-Figure 1 is a transverse section, and Fig. 2 a top View, of a shortpiece of hose in accordance with my invention, such hose, with theexception of the re-enforce to be hereinafter explained, being madeessentially as repre sented, described, and claimed in Letters PatentNo. 158,631, granted to me January 12,

. 1875, without being fastened at its tops by nails or rivets, whichmay, however, be used.

In carrying out my invention, I protect the outer lap by applying to it,while the hose is being made, a strip of vulcanized rubber orcomposition or cloth covered with such, and

folded at or near its middle, such. strip being to embrace the lap onboth of its opposite surfaces, and to extend beyond it. Where extendingbeyond the edge of the lap the lapped parts of the strip or re-enforceare to be connected together and to the hose. The part of the re-enforcegoing over the lap is to be ccmented thereto, and the part going underit also to be cemented to it and to the hose-body.

In the drawings, A denotes the hose, and B the reenforce, which, insteadof being a strip simply lapped across the edge of either folded statebeyond the edge of the lap, and

that the remainder embraces the lap on its opposite surfaces.

The re-enforce so applied, when vulcanized,

not only insulates the edge of the lapfrom water, but, very much more,prevents it from being injured or turn up than would a strip simply bentaround the edge and a little under the lap, and also over its uppersurface.

In order to protect from water the inner edge of the inner orlower lap,I carry around i such edge and lap on the lower stratum f, of rubber,and cement thereto and the edge a portion, h, of'the upper rubberstratum g.

I do not claim a hose made of a rubber-surfaced strip lapped together atits two op positc edges, and provided with a covering welt to each edgeof the strip.

I claim as my invention- A hose, A, made of cloth, covered withvulcanized rubber or composition, and provided with a re-enforce orstrip, B, as described, folded back upon itself, and applied to oppositesides of a lap, a, and extended beyond its edge, and cemented togetherin the extension,

and to the "parts of the hose in contact with v such re-enforce, allsubstantially as shown and explained.
